A short review on the synthesis of bimetallic nanoparticles using plant extract

Abstract

With the emerging catalytic, optical and medical applications of nanoparticles, there is a growing demand for green synthesis methods to ensure consumer safety. Among bio-organisms, plants are the major source of reducing agents due to the simple procedures and inexpensive cost required. This paper presents a short review of bimetallic nanoparticle synthesis using several plant extracts. Biosynthesis studies examining pH and concentration of plant extract, reaction temperature, and ionic ratio are also presented to provide a clear understanding of how these parameters affect the formation of nanoparticles.
